10 kv transformer
well, i didn't get shocked by it, but I sure built it.
I took an old transformer from a battery charger (one of those 75 amp start jobs) and rewound the secondary and made it the primary. I ran this thing in a large pot of wesson oil. (It drew 20 amps at 120volts and would boill 2 gals of oil in a matter of 10 seconds) The lights in the house would dim. I ran some wire to my brothers' bedroom before he got home. After he laid down, i fired it up for a few secs. at a time. The arc across the ends scared the freakin s**t out of him. He refused to go to sleep that nite.
No I did not actually shock him. It would have killed him for sure. I made a lot of wierd, but way cool things as a child.
2 liter bombs are way cool too. Just r-502 is all you need
